Nebraska science god Aaron ALAI, an expert in the theoretical side of wildlife ecology, demonstrates Stochasticity, a music installation that lets you draw musical notes with water:

The name of the piece is called Stochasticity. I built it to demonstrate the randomness that humans introduce into very precise systems.

When someone uses my art piece they are directly interacting with a very precise electronic tool. It produces musical tones based on the amount of resistance sensed in trails of water. The resistance changes unpredictably, and thus this is where the variability in the system arises from. The water evaporates, the user will flex their muscles, their hearts will pump blood at varying rates, and the conductivity of their skin will change. All of these variables change the placement of the notes in the water and make the system unreliable. I found it interesting that even though imperfect animals such as ourselves are plagued with randomness, we are capable of producing reliable highly precise tools that we can indirectly interact with.

I have included it here on my webpage because it fits within my philosophy rather well. The concept of resistance is commonly explained with analogous personal experiences, a common experience involves turning on a water faucet, wider openings allow more water to flow through and more water means more electricity. My art piece bridges the gap between personal experiences and the complexity of resistance. The user can visually see themselves changing the resistance of the electronic system while receiving an instantaneous auditory response. They become the resistor and can manipulate that variable in a familiar way.

It’s fascinating as an art installation – but can you imagine larger, multi-player temporary electronic instruments – made of water?

This is a demonstration of the RADCASTle, a monophonic synthesizer using analog sound-generating circuitry driven by a microcontroller.

This was a ECE4007 Senior Design Project at Georgia Tech in the Fall 2008 semester. The team members were Robert Estelle, Logan Snow, Hoan To, and Greg Hartl.

The analog boards were purchased from Ray Wilson of Music From Outer Space. The team developed custom boards to interface the various analog synth boards with a PIC microcontroller through digital-to-analog converters.

This video demonstrates a modular synthesizer sequencing video along with sound.

modular synth + arduino micro controller + MAX/Jitter video player.All of the sound is coming from the modular synth. The analog sequencer is sending a varying voltage to the arduino which is communicating with the computer and tweaking a video player I made in Max.The video is a promo clip from a balloon enthusiast website.
